About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1558394082. Listed at 12 retailers as of October 30, 2026, with prices from HK$15,166 to HK$35,094, a HK$19,928 spread on the same certified stone. NZ Jewellers lists it at HK$35,094. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
